Pre Installation Instructions (cont.)
INSTALLATION
• Siting of the VELOPEX
When using the machine in daylight or a darkroom, avoid sources of intense light.
Do not mount the unit under a window, fluorescent light or flood lamp.
IMPORTANT NOTE: A well ventilated position is mandatory.
The ambient temperature must be below 80oF (27oC).
Prevent siting the machine above or near other electrical or mechanical equipment.
Surfaces susceptible to water or chemical damage should be avoided, such as
carpeted areas.
1. COUNTER
a. Use a stable and level counter that will support a weight of at least
100 lbs. (50 Kg.).
b. When the machine is filled with chemicals, make sure the stand does not
rock or shake. NEVER move the machine with chemicals in the tanks.
2. ELECTRICAL SUPPLY
a. 115Vac 60Hz, 10A, 1150W (USA)/230Vac 50Hz, 10A, 1150W (World Wide).
b. The power source must be within three (3) feet (1m) of the machine. It
should be easily accessible for operation and maintenance.
WARNING: X-ray radiation can be harmful to patient, technician and dentist.
Inadequate lead shielding of the darkroom or film storage area will also cause
fogging from exposure of films to stray x-ray radiation. Consult your local
codes, Health Department or Dental Equipment Dealer for proper construction
of darkroom or placement of film processing equipment in the vicinity of x-ray
radiation sources.

when the red light is extinguished.
TIP:
The time taken to achieve the
correct temperature depends on the
room temperature (usually 10-15 min.).
TIP:
Intra-XE has no heating and
therefore no temperature indicator. It
relies on ambient room temperature of
20oC - 25oC.

Chemical
Contamination
Mixing of Developer
Check temperature of Developer and Fixer tanks. These are generally set at: Developer 82ºF
(27.5ºC), Fixer 82ºF (27.5ºC). If the Developer temperature is significantly higher, it could lead to
dark film. Switch off the machine and call for service.
Check Expiry date on film box to ensure films are not out of date. (Keep films in cool, dry place:
excessive heat can cause premature ageing of film).
Film Expired
Temperature (XE
excluded)
Check whether films have been stored too close to X-ray source, and re-locate/replace.
Check that window cover on loader has been correctly replaced and check at hand entry ports
to ensure there is a good light seal around the wrists - if not, call for service.
Do not remove your hands out of the hand entry ports before the film has fed completely
into the machine (fog at one end only of the film indicates premature removal of hands from
daylight loader).
Close to X-ray Source
Light Leaks
Check that the dark room is light-tight, and that the safelight is sound (e.g. process a test film
with safelight off ).
Dark room not LightTight
When the Daylight loader is used, ensure that the machine has not been sited in direct sunlight
or in intense lighting conditions (e.g. directly under spotlights or strip lights).
Check that the top lid is firmly in place.
Lid Open
Test for light fog by feeding an unexposed film through the machine. It should process as a transparent piece of film base and there should be no
shadows or blackness on it. REGULAR USE OF VISCHECK IS THE BEST TOOL FOR EARLY DIAGNOSIS OF PROCESSING AND X-RAY PROBLEMS.

MICRO PROCESSOR PCB OPERATION
The PCB performs the five functions listed below:
1. At switch on, or whenever the start button is pressed, the drive motor and
the dryer run for 8 minutes.
2. The dryer is controlled to an output temperature of 147°F/60°C.
3. The Developer and Fixer tank heaters are independently controlled to a preset temperature whenever the mains power switch is on (XE excluded).
4. If either of the temperature sensors controlling the two tank heaters
becomes open circuit or short circuit, the ready LED on the PCB will flash
once a second(XE excluded).
5. If the dryer fan stops or its air inlet grill (on the rear face of the processor)
is obstructed, the dryer element will be switched off automatically before
it overheats.
Settings and Adjustments:
1. The dryer is controlled by means of a thermostat in the hot air stream,
which switches the dryer element between full power and a reduced
power level. This reduced power is achieved by switching the element on
and off 60 times a minute for a proportion of the time. This proportion
is set to 20% and is adjustable between 20% and 80% by means of the
%ENERGY potentiometer (Fig 1, page 13).
2. The safety shutdown of the dryer element is achieved by means of a “Trip”
sensor in the heater housing. This is reset by unplugging the processor, and
then plugged in again after a 10 second pause.
3. The chemicals in the Dev. and Fix. tanks are kept at a set temperature
by means of a thermistor in each tank. These temperatures are set to
82°F/27.5°C (Developer) and 82°F/27.5°C (Fixer) and are adjustable by
means of the DEVELOPER and FIXER potentiometers between 72.5°F/22.5°C
and 90.5°F/32.5°C.
